Proportional Directional Valve 4WRZE10E1-25-7X/6EG24K31/A1D3M - Bosch Rexroth R901166107

When pilot pressure and pilot return are provided centrally, the 4WRZE10E1-25-7X/6EG24K31/A1D3M is the matching version: supply and return both run externally. With 25 l/min nominal flow, spool symbol E1 and 315 bar operating pressure it works at the lower end of size 10.

Benefits

• External pilot supply and external return separate the pilot stage completely from the main circuit.
• 25 l/min nominal flow, maximum flow up to 170 l/min.
• Spool symbol E1, command value +/-10 V, on-board electronics on 24 VDC.
• Operating pressure up to 315 bar, mounting pattern ISO 4401-05-05-0-05.
• Built-in pressure reducing valve holds pilot pressure constant.
• Weight 8.48 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

This variant belongs in plants with their own pilot circuit, such as large presses and test fields with central pilot pressure supply. Pilot pressure then stays independent of the working pressure of the axis. The Y line runs to the tank without back pressure.
